ABSTRACT We focus here on the problem of poor real-time performance and low accuracy of seed box allowance detection during wheat sowing operations, and present a real-time weighing system for a seed box allowance. The proposed weighing system obtains the seed box allowance using an ultrasonic sensor and load cell, and displays it in real time via a computer. Based on the proposed weighing system, the weighing structure is also designed for the seed box. At the software level, three filtering methods are proposed to condition the signal, namely mean filtering, median filtering, and the acceleration method, and models of these three filtering algorithms are implemented in MATLAB/Simulink. Experiments to assess the accuracy of the system and filtering algorithm were carried out on the test bench; the results show that the system error is initially in the range −16.3 g to 63.8 g, and is reduced to the range −13.4 g to 15.1 g after correction. No significant difference between the three filtering algorithms is found, but since the acceleration method can improve the response speed of the system, this is selected as the final filtering method. realtime operations cell computer level signal MATLABSimulink MATLAB Simulink MATLAB/Simulink bench 163 16 3 −16. 638 63 8 63. 134 13 4 −13. 151 15 1 15. correction found −16 6 −13 −1 −

Abstract LncRNAs are known to be key regulators in the initiation and development of diverse cancers. Whether LINC00115 is involved in the regulation of gastric cancer (GC) progression remains unclear. Here, we aimed to show the function of LINC00115 in GC. RT-qPCR was used to measure gene expression in GC tissues and cells. Colony formation, EdU, TUNEL, and wound healing assays were used to analyze cellular processes in GC. The in vivo GC xenograft model was established. We observed that LINC00115 was highly expressed in GC. Functionally, silencing LINC00115 inhibited GC cell proliferation, and migration but facilitated GC apoptosis. Mechanistically, LINC00115 sponged miR-212-5p, while miR-212-5p targeted ATPAF1 in GC cells. Rescue assays showed ATPAF1 overexpression countervailed the inhibitory role of LINC00115 depletion in GC progression in vitro and in vivo. Overall, LINC00115 promoted GC progression by upregulating ATPAF1 via miR-212-5p. cancers LINC LINC0011 (GC unclear Here RTqPCR RT qPCR cells formation EdU TUNEL established Functionally proliferation apoptosis Mechanistically miR2125p, miR2125p miRp miR 212 5p, 5p p ATPAF Overall miR2125p. 5p.

OBJECTIVES: To clarify differences between solitary pulmonary inflammatory lesions and peripheral lung cancers with contrast-enhanced computed tomography. METHODS: In total, 64 and 132 patients with solitary pulmonary inflammatory masses/nodules and peripheral lung cancers, respectively, were enrolled in this study. Their computed tomographic findings were summarized and compared retrospectively. RESULTS: Compared with the peripheral lung cancers, the inflammatory lesions were located closer to the pleura (p<0.0001). The majority of the inflammatory lesions were patchy and oval-shaped (82.8%), whereas most of the tumors were lobulated (82.6%). Almost all the inflammatory cases were unclear (93.8%), whereas most of the tumors had spiculated margins (72.7%). Computed tomography values were significantly higher for the inflammatory lesions than for the cancers (p<0.0001). More than half of the inflammatory lesions had defined necrosis (59.3%). Furthermore, 49.2% of the cancers enhanced inhomogeneously, but only 24.6% had ill-defined necrosis or cavities. The peripheral zones of 98.4% of the inflammatory lesions and 72.7% of the tumors were unclear, with peripheral scattered patches (92.2%) and beam-shaped opacity (66.7%) being the most common findings, respectively. Adjacent pleural thickening was more frequent for the inflammatory lesions than the cancers (95.3% vs. 21.1%, p<0.0001), whereas pleural indentation was found in 67.4% of the subjects with cancer. In addition, hilar (p=0.034) and mediastinal (p=0.003) lymphadenopathy were more commonly detected in the cancers than in the inflammatory cases. CONCLUSIONS: Contrast-enhanced computed tomography findings for pulmonary inflammatory lesions and peripheral lung cancers were significantly different in many aspects. Developing a comprehensive understanding of these differences is helpful for directing their management.

Quatro novas dibenzociclooctadienolignanas, neglectalignanas A-D (1-4), juntamente com dezenove compostos conhecidos (5-23), foram isolados das hastes de Schisandra neglecta. Suas estruturas e esteroquímicas foram elucidadas por métodos espectroscópicos, incluindo as técnicas de ressonância magnética nuclear (RMN) de 1D e 2D, e espectrometria de massas de alta resolução com ionização por electrospray (HR-ESI-MS). Avaliou-se as atividades anti-HIV e a citotoxicidade dos compostos 1-4 , e os resultados mostraram que os compostos 1-4 apresentam atividadade anti-HIV moderadas com valores de índice terapêutico (TI) acima de 61,7, 22,6, 57,7 e 27,9, respectivamente, e atividades citotóxicas fracas contra algumas das linhas celulares selecionadas.

Four new dibenzocyclooctadiene lignans, neglectalignans A-D (1-4), together with nineteen known compounds (5-23) were isolated from the stems of Schisandra neglecta. Their structures and stereochemistries were elucidated by spectroscopic methods, including 1D-, 2D-nuclear magnetic resonance (NMR) and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) techniques. Compounds 1-4 were evaluated for their anti-HIV activities and cytotoxicities. The results revealed that compounds 1-4 showed moderate anti-HIV-1 activities with therapeutic index (TI) values above 61.7, 22.6, 57.7, and 27.9, respectively, and weak cytotoxic activities for some selected cell lines.

Immune reconstitution inflammation syndrome typically occurs within days after patients undergo highly active anti-retroviral therapy and is a big hurdle for effective treatment of AIDS patients. In this study, we monitored immune reconstitution inflammation syndrome occurrence in 238 AIDS patients treated with highly active anti-retroviral therapy. Among them, immune reconstitution inflammation syndrome occurred in 47 cases (19.7%). Immune reconstitution inflammation syndrome patients had significantly higher rate of opportunistic infection (p < 0.001) and persistently lower CD4+ cell count (p < 0.001) compared to the non-immune reconstitution inflammation syndrome patients. In contrast, no significant differences in HIV RNA loads were observed between the immune reconstitution inflammation syndrome group and non-immune reconstitution inflammation syndrome group. These data suggest that a history of opportunistic infection and CD4+ cell counts at baseline may function as risk factors for immune reconstitution inflammation syndrome occurrence in AIDS patients as well as potential prognostic markers. These findings will improve the management of AIDS with highly active anti-retroviral therapy.
